E.g.
Girl Scouts: allowed to be girls only
Boy Scouts: now “Scouting” because girls are allowed
My intramural sports in college had coed and women only teams
(Source: My sister and her friends were the type that would have thrived in boy scouts, but they had to join a "venture crew" run by the same scout leader as our boy scout troop)
The chance to obtain Eagle Scout status is itself more exciting. It difficult to deny that it is one of the best leadership programs for children available. The girl scout equivalent is not even close to producing the leaders the Eagle Scouts do. They also have their own network for eagle scouts to connect. It can be an opportunity to get into a Good ‘ol Boys club (future business & money connections) before moving out of their parent’s house.
If a male or female wants to learn more about extracting money from family/shoppers by selling cases of cookies, or learn about female social empowerment and financial skill, instead of learning leadership through self reliance/accountability skills mixed with teamwork, then why not let them choose the programs they want? -- but they are different. Their Gold Award is nothing like earning Eagle Scout status.
Turns out some are allowed to have special clubs, but others not so much. And we only have societal perception of women to blame; the thing they're relying on for all this "they need their own space to protect them" is demeaning, imo. Besides the fact that the majority of victims of crime are male (and before someone points out that the majority of criminals are also male - did you know that's a sexist statement to make? It's judging an entire sex by the actions of individuals).
